3 Ways to Generate Random Number with Decimals in Excel
1. Generate Random Number with Decimals Using Excel RAND Function
You can use the RAND function in excel to generate random decimal numbers. It returns a random number greater than or equal to 0 and less than 1.
- First, enter the following formula in cell B5.
- Then, drag the Fill Handle icon to populate the entire range (B5:G10) with the formula.
- Alternatively, you can select the entire range first. Then type the formula.
- After that, press CTRL+SHIFT+ENTER to get the desired result as follows.
- Now, you can use Cell Formatting to limit the decimals to a certain number (4) of digits. Alternatively, you can nest the function inside the ROUND function to get the job done as shown in the following picture.
- Now imagine you want to get random decimal numbers between 50 (lower limit) and 100 (upper limit). Here, the difference between the numbers is 50 (upper limit – lower limit). Then, you can use a generic formula as follows.
- To see the desired result, first select the entire range. Then, apply the following formula by using CTRL+SHIFT+ENTER.
2. Produce Random Decimal Numbers with Excel RANDARRAY Function
You can also use the RANDARRAY function in excel to produce random numbers with decimals. This function returns an array of random numbers with a specified number of rows and columns between two specified numbers. Unfortunately, this function is available to Office365 users only.
- Just enter the following formula in cell B5 to get the result shown in the picture below.

3. Random Number with Decimals Using RANDBETWEEN & RAND Functions in Excel
Using the combination of the RANDBETWEEN and RAND functions in excel can be another alternative for this purpose. The RANDBETWEEN function returns random numbers between two specified numbers.
- First, select the entire range where you want to generate the random decimal numbers.
- Then type the following formula and then press CTRL+SHIFT+ENTER. The -1 in the formula prevents the RANDBETWEEN function from returning the maximum number (800). This way the final output won’t be greater than the maximum limit.
After that, you will see the following result.👇
Produce Random Whole Numbers in Excel
You can use the RANDARRY function to generate random whole numbers too. Just enter the following formula in cell B5 as shown below.
- Alternatively, you can use the RANDBETWEEN function for that purpose. First, enter the following formula in cell B5. Then, drag the Fill Handle icon to apply the formula to the entire range of cells.
Things to Remember
- The RANDARRAY function is only available in Office365.
- Always remember to press CTRL+SHIFT+ENTER to enter the array formulas.
- Be careful to correctly use the lower and upper limits when you want to get the random decimal numbers between two negative numbers. For example, you should use -500 as the maximum and -1000 as the minimum and not the other way around.
